CLAMPING BRACKET Filed Dec. 23, 1930 Jfif wwf/mm Patented Feb. 14, 1933 UNITED STATES PATENT OFFICE] ROBERT HETHERINGTON, OF SHARON HILL, PENNSYLVANIA CLAMPING BRACKET Application iled December 23, 1930. Serial No. 504,235.

pable of supporting a pasteboard or metalVV carton box or bucket. j A further purpose is to provide a bracket with an adjustable arm for supporting a package that can be easily attached or detached at any desired height to a supporting structure luider a Sink.

A further purpose is to provide a detachable bracket, supporting an arm at right,

angles which can be adjusted laterally, the arm having forked spring members with downwardly directed spring lingers which fit the interior of a package or container.

A further purpose is to provide a fitting that can be clamped to a supporting stand of a sink or the like, to support clamping bracket arms of an adjustable bracket, allowing for revolving movement of both the bracket and the adjustable bracket arm, tov

bring the arm into and out of position of use.

Describing in illustration but not in limitation and referring to the drawing:

Figure 1 is a perspective view of a kitchen sink showing my improved bracket in position of use on a drain pipe.

Figure 2 is a top plan view of the bracket shown in Figure 1, the bracket being attached to the drain pipe which is shown in section.

Figure 3 is a sectional elevation taken on the line 3-3 of Figure 2.

Figure 4 is a sectional elevation similar to Figure 3 but showing different supporting and clamping structures.

Figure 5 is a top plan view similar to Fig- Y away.

Figure V6 is a section on the line 6-6 of Figure 5.

- Figure 7 is a side elevation of a modified laterally and rotatably adjustable bracket provided with a hooked arm.

In the drawing like numerals indicate like parts. w

Y Many times it has been found desirable to have a container or shelf lbeneath or near kitchen sink to hold cleaning material.

My invention is intended to do away with the container or shelf mentioned above andto Vuse instead, a bracket fastened underneath a sink, the bracket having an arm that can,A

be moved laterally and which will, when in its extended position, project far enough forward to be within easy reaching distance of a person working at the sink.

I also provide a bracket that can be easily and quickly secured to a drain pipeor any supporting stand beneath a sink and will at the same time be adapted to convenient position`ing. i

In one of the forms shown my bracket is be moved inwardly and outwardly from beneath a sink and in the other form the bracket can be vrotated about a pipe and also can be moved laterally. I find insome installations it is not necessary to have the form which so moves both rotatably and laterally. l

In the forms shown in Figures 1, 2 and 3,

I have shown a bracket 10 fastened to a pipe 11. The bracket 10 hasY forwardlyextending These arms 12 and 13 are turned laterally Vat 111 and 15 some distance from the drain pipe` 11, and are turned forwardly at 16 and 17 to form bearings 18 and 19 yfor laterallyY moving arm 20. Arms 12 and 13 maybe fastened to or detached from the pipe 11 by means of a bolt 21 and thumb nut 22.

' HIn Figure 2 the laterally movable arm 20 is extended at 23 and its extended end has y secured thereto bowed spring extensions 24: and 25 having downwardly extending spring fingers 26 and 27 which engage the sidewalls 28 of a carton or the like 29. The spring eX- tensions are effective to resilientl press the side walls outwardly, if the box lie initially narrower than their spacing. This holds a narrow box open in circular or elliptical shape, giving better access to the contents.

With wider boxes the support is still lateral- 5 ly resilient but the need for this is not so great.

The laterally movable arm 2O is provided on its opposite end witha stop in' the -formI J:

of a pin 30.

Figure 3 shows clearly the spring fingers '26 and 27 extending downwardlyfromthe bowed spring extensions 24: and 25.l It. will 1 benoted that the contact points 31'fan'd 32 p v-engageone side ofthe walls 28 ofV the box 29 and the bowed spring arms zit 'and 25 "engage the other side of wall 28 of the box 29. The above construction provides desirable gripping means to hold the box in position,

K so that the user may insert his hands without danger of the box being dropped on the Hoor. In the forms shown in Figures 4, 5 andv I l #horizontal-1 barslidable in the bracket and posed bracket having spaced arms, spring clamping means for holding the spaced arms in position about a pipe, spring arms supported by the bracket and downwardly open spring fingers terminating the spring arms 7o and adapted to engage the open top of a container and to support the container.

%^`.R5BER 'HETHERINGTON Uhave illustrated an additional split Vclamp -itting 33. This tting is Vmade in half'ring 30- sections 34 and 35 each of which are'provided' with upper and lower cooperating ears 36 and 3T. Through these ears I insert tightening screws 38 which :fasten the"bearing clamp 33 to the 'drain pipe orsupport.

-Between these upper and lowercooperi ating'ear members 36 'and 37 ofthe bearingV clamp 33 I provide a reduced bearingsurface 39 about which the'clamping arms 12 and 13 are firmly held in place by a spring` clip 40 40 forcedover the arms 12 and 13 of the bracket 11 tending to pull the arms 12' and 13 in- "fwardly to tighten the bracket 11 tothespipe 10; otherwise the construction is V.identical with that shown in Figures 1 to 3 inclusive. -I have shown another form' of the many flvariations my invention may assume in ,Fig-
